specification of Letters Iatent. Patented Mai. 28, 1922.

Application filed March 10, 1920. Serial No. 364,825.

To all whom it may concern.

Be it known that I, WILLIAM CHARLES Crooner, a subject of the Kingdom of Great Britain, residing at 2 Greystone Court, Ealing, in the county of Middlesex, England, have invented certain new and useful Improvements in Fasteners for Loose Sheets of Paper or other Material, of which the following is a specification.

This invention comprehends a fastener for loose sheets of paper and other material, comprising a cord, a disc or plate fixed on one end of said cord a second disc or plate adjustably mounted on said cord, said adjustable disc or plate having a tapering slot extending from its periphery to its centre for the passage of the cord, and a cleat carried by said adjustable disc or plate for fixing the cord to same.

This invention further comprchends a fastener for loose sheets of paper and other material, the combination of a cord, a disc or plate fixed at one end of said cord, an adjustable disc or plate adapted centrally to engage the cord, and a cleat located to the one side of the point of engagement with the cord, said cleat being cut and pressed out of the sheet metal of which the adjustable disc or plate is composed.

In the accompanying drawing, which illustratcs this invention I Figures 1 and 2 are views in plan and elevation of the improved adjustable disc or plate.

Figures 3 and e are similar views of the cord and fixed disc or plate.

Figure 5 is a view in plan showing the attachment of the cord to the adjustable disc or plate, and Figure 6 is a view in plan showing a modification of the adjustable disc or plate.

Throughout the views similar parts are marked with like letters of reference.

The cord a and fixed disc or plate 6 present no novel features and are of the usual type the cord being threaded through a hole in said disc or plate and having a knot at one end to engage said disc or plate and a tag at the other end to facilitate passing it through the sheets. i l

The adjustable disc or plate 0 is provided with a tapered slot 0 which extends from its periphery to its centre. Said slot may either be truly radial as shown in Figures 1 and 5, or partly radial and partly tangential, as shown in Figure 6. The slot 0 gradually tapers towards the centre of the disc or plate as shown in the accompanying drawing, the smaller and inner end of said slot being of such a size relative to the cord that a wedging action takes place between said parts when the cord is drawn under the cleat and thus additional security is obtained.

At a convenient distance from the centre of the disc or plate 0 is formed a cleat (I which made slightly arched or curved and has a depression (P at or near its free end.

The cleat (Z can conveniently be formed by cutting and pressing out a tongue as shown in Figures 1, 2, 5 and 6 of the accompany ing drawing.

hat I claim as my invention and desire to secure by Letters Patent is A fastener for loose sheets of paper or the like, comprising a cord, having stop means at one end and a disc having an inwardly tapering slot extending from the center to one side thereof to receive and grip the cord when one part of the latter is at right angles to the plane of said disc,

and also having a cleat spaced from the inner end of said slot to secure the end of the cord.

In witness whereof I my hand.

WILLIAM CHARLES OROCKER,
